Multifunctional Mini Filter for Small Fish Tank

Instead of relying on a single narrow outlet, the horizontal spray bar sends returning water through multiple small openings across the aquarium surface.

This moving-water effect helps circulate the upper water layer and creates visible surface agitation while the compact filter body remains mounted along the side of the tank.

The internal pump draws aquarium water through the filter section, where the media can capture accessible suspended debris before the water is returned through the upper outlet.

By combining filtration and water movement in the same compact housing, the unit avoids the need for separate circulation equipment in many small-tank setups.

Small aquariums need filtration too, but oversized equipment can dominate the tank visually. The product is offered in two compact heights, approximately 12.2 cm for M and 14 cm for L, while maintaining a narrow body.

The product image compares the filter's overall length with a smartphone, helping show how little space the unit occupies.

The product uses suction-cup mounting points to hold the filter against a smooth aquarium wall while it operates. This allows the main body to sit vertically along the glass rather than taking up a broad footprint across the aquarium floor.

The image also shows the wired power connection and detachable structural components used to assemble and position the unit.

Once installed, the vertical filter body sits close to the glass while the upper spray bar returns water across the surface. This keeps the main filtration equipment concentrated along one side of the aquarium and leaves more of the central viewing area open.
